How do I ensure the Butler Creek Element Size 2 fits my specific riflescope eyepiece?

The BCEEP2 is engineered exclusively for ocular bells with an outer diameter measuring between 42 mm and 47 mm. You should measure your scope's outer eyepiece diameter with digital calipers before purchasing, as eyepieces under 42 mm require the Size 1 cap and those larger than 47 mm need alternative sizing.

Will the flexible rubber sleeve and latch hold up against heavy recoil on a magnum hunting rifle?

Yes, the multi-flex friction sleeve and heavy-duty ridged polymer construction are multi-calibre rated to withstand severe recoil without slipping or shifting position. It handles heavy-hitting centrefire and magnum calibres reliably while keeping your ocular lens sealed against red dust and moisture in the Australian bush.

What insert disks come included, and how do they affect targeting in wet weather or bright sun?

The BCEEP2 features three interchangeable lid insert disks to suit your shooting conditions. It includes an opaque black disk for standard glare and sun blocking, a clear lens disk for rapid target acquisition during wet or drizzling conditions, and a customisable ballistic data disk that accepts drop charts from the online template generator.

Does this product require any electrical safety compliance or Australian certifications for use?

No electrical compliance or certifications such as SAA or RCM are required because the BCEEP2 is a passive, non-powered mechanical accessory. It operates entirely without batteries or electrical inputs, making it fully legal and unrestricted for use across all Australian states and territories.

Scope Eyepiece Cap - Butler Creek BCEEP2

The Butler Creek Element Flip Open Eyepiece 2 42-47mm (MPN: BCEEP2) is a rugged, passive mechanical optic cover designed to protect riflescope ocular lenses from dust, moisture, and impact damage. Built with a heavy-duty moulded polymer lid, stainless steel pivot hardware, and a flexible rubberised multi-flex sleeve, it provides a secure friction fit over ocular bells measuring 42 mm to 47 mm (1.65" to 1.85") in outer diameter. The cap features dual locking positions at 180° upright and 270° folded flat against the scope body, preventing field-of-view obstruction during shooting.

Who is the Butler Creek Element Flip Open Eyepiece 2 42-47mm for?

Australian Bush Hunters — Needs a tight-sealing riflescope eyepiece flip cover that stretches across 42 mm to 47 mm ocular bells to seal out fine red dust, mud, and high-UV glare during extended field stalks.
Pest Control Shooters — Requires an interchangeable clear lens insert on a ~25.4 mm deep eyepiece cap to acquire targets rapidly in sudden rain and drizzle without exposing bare glass to water droplets.
Precision Rifle Shooters — Relies on the modular ballistic data disk integrated into this 100 g optic cap to reference custom drop charts instantly while cycling dual-position 180° and 270° lid openings.

Less suitable for: Riflescope ocular bells measuring under 42 mm outer diameter (which require a smaller Size 1 37–42 mm flip cap) or scopes with eyepieces exceeding 47 mm (which require a dedicated larger-diameter optic cover).
